feat: Add CallTraceBar for real-time call tracing in TUI #20068
Description
Description
Add a CallTraceBar component to the TUI that provides real-time visibility into all calls happening during a session - including LLM calls, tool executions, and plugin/agent operations.
Problem
Currently, when using opencode with plugins (like oh-my-openagent), there's no visibility into:
- Which agent is active
- What tools are being called
- LLM call details (model, tokens, cost, duration)
- Plugin operations (subagent spawning, mode injection)
Users have to rely on console logs or guess what's happening.
Proposed Solution
A collapsible CallTraceBar at the top of the session view that shows:
- User messages (collapsible)
- LLM calls with model, tokens, cost, duration
- Tool calls with expandable input/output
- Plugin operations (agent calls, subtasks)
Each trace item shows timing, status, and is expandable for details.
Design
┌─ CallTrace ──────────────────────────────────────────┐
│ 📋 User │ 🤖 LLM │ 🔧 Tools │ 🔌 Plugin │
│ 3 items │ 5 calls │ 12 calls │ 2 agents │
└──────────────────────────────────────────────────────┘
Click a category to expand and see individual trace items with timing, status, and expandable details.
Benefits
- Real-time visibility into all session operations
- Debug plugin behavior easily
- Track costs and token usage
- Understand agent delegation flow
